Improper received data in 57600 baud rate

I have attached one Xbee in my PC which is erceiver and attached another Arduino+Xbee in another PC. (Sender). My receiver is getting proper message when the baud rate is 9600. But using the same sketch my receiver is getting improper data at baud rate 57600 which is only a dot. The set up is simple. I am just printing a simple text "Test";

Changes made when using 57600 baud rate.

  1. Serial.begin (57600) in the sketch.
  2. In the XCTU (PC side)I have chosen COM port and change baud rate to 57600.

Is there anything more do I need to do make it working in baud rate 57600?

Please do not cross-post. Other topic deleted. Replies go here.

How about telling the Xbee about the new baud rate.
